World Class Birimian Gold Belt Exploration Update – Kouroussa Project and Additional Information

Volt is pleased to provide an exploration update on its Guinea Gold Projects located in the Siguiri Basin, which forms part of the richly mineralised West African Birimian Gold Belt.


  • Volt and Sahara geology teams have completed the desktop study phase for new Guinea Gold Projects and commenced initial field exploration works.
  • The desktop studies and initial site visits have identified the presence of Birimian greenstone sequences in all Kouroussa Project permits. The geology is similar to Predictive Discovery’s (PDI:ASX) permits and the nearby Kouroussa and Kiniero Gold Projects currently in development.
  • In the Kouroussa area, significant artisanal workings have been mapped along a NE interpreted structural trend through the Kouroussa and Fadougou permits. Gold panning of material from one of the artisanal pits produced visible gold. This structural trend hosts the Predictive Discovery and Cassidy Gold Projects.
  • Volt has extended its Kouroussa West permit area to the south, doubling its size. Active small scale gold mining has been identified 1.5km south of the permit area.
  • Historical data compilation of the Konsolon Permit has identified multiple “gold in soil” anomalies between 1 to 2.5km in length. This project is located ~20km West from Nordgold’s Lefa Gold Mine which has resources and reserves of over 6 million ounces.

Volt Resources Limited (ASX: VRC) (“Volt” or “the Company”) is pleased to provide an exploration update on its Guinea Gold Projects located in the Siguiri Basin, which forms part of the richly mineralised West African Birimian Gold Belt. The geology team has finalized desktop studies on most of the Guinea Permits.

The teams have now commenced field exploration activities. Initial activities include geological mapping and sampling of outcrop and artisanal workings and collection of soil samples. This will be followed up
shortly with Auger Geochemistry and then reconnaissance drilling.

Desktop studies and initial ground works have confirmed the presence of extensive Birimian Greenstone sequences in all the permits including mineralised quartz veining, active artisan mining and extensive
lateritic cover.

Guinea Projects and Permits

Volt has six permits in Guinea’s highly prospective Suiguri Basin and has formed them into three regions – the Kouroussa Project, Mandiana Project and Konsolon Project. See Figure 1 below for the project and permit locations.

The Kouroussa Project is formed by three permits, the Kouroussa, Kouroussa West and Fadougou permits.The Kouroussa and Kouroussa West permits border the PDI permit which was the subject of a recently
announced discovery of high-grade gold mineralization.

The Konsolon Project constitutes one large permit. The permit has a NW-SE trending soil geochemical anomaly identified by previous explorers.

The Mandiana Project is formed by the Nzima and Monebo permits. The Nzima permit area surrounds the Nzima gold deposit which is operated by small scale miners.

Kouroussa Project

Desktop studies
The studies included historical data compilation, GIS and Remote Sensing, and conducting desktop interpretation of the data to generate initial targets.

  • Review of previous geological maps covering the Kouroussa Project (Kouroussa, Kouroussa West and Fadougou permits) have identified a series of EW (Fault 1 and Fault 2) trending faults displaced by a second set of NS (Fault 3) trending fault systems. A final NE sequence of interpreted faults is aligned with the main know deposits in the region. Gold mineralization seems to be associated with the fault systems which cut through the Kouroussa and Kouroussa West permits (see Figure 2 below).
  • Large parts of the permits are dominated by Birimian meta-volcanic and meta-sedimentary sequences. The areas have been identified as very prospective as they have similar geology to the nearby Predictive Discovery (PDI) and Cassidy Gold(Private) gold development projects.

Field works
The geology teams have commenced field work activities on the Kouroussa Project permits. Activities have included site visits to all the permits and collection of soil and rock samples.

Kouroussa permit. A site visit to the permit has identified an area of artisanal mining activities in the NE border with the Kouroussa Mine known locally as the “World Bank”.

Several artisanal working clusters have been mapped in the area measuring approximately 600 metres by 800metres. The workings seem to be an extension of mineralization from Cassidy Gold’s Kouroussa Gold Project.

The artisans are mining gold from lateritic cover. The area coincides with an interpreted NE Fault sequence. The area is covered by mineralized laterites. Grab sampling from these artisanal workings is in progress and
will be sent for assaying.

The photos below are of artisanal workings and Figure 3 below shows the location of identified artisanal workings on the Kourassa Permit.

Kouroussa West permit. The permit is in an isolated area covered by shrubs and small trees. The team has visited the area twice to conduct geological reconnaissance. Due to the exploration potential identified during the site visits, Volt has doubled its permit area from the initial size of 47.9km2 to 99.83km2

  • Old artisanalshafts/pits and active workings were observed about 1.5km to the south of the permit boundary. The shafts and pits are following a 420 NE trending mineralized quartz veining system with mineralized lateritic cover.
  • The permit area is covered by lateritic cover materials with quartz fragments scattered in the area. The geology is a continuation ofthe geology observed in the artisanal workingssouth of the permit.
  • Some gold mineralization is associated with sulphides in quartz veins. Artisans are extracting their gold from both laterites and quartz veins.

Fadougou permit. The permit is covered by small trees, bushes and shrubs. The team has visited the area twice to conduct geological reconnaissance.

  • The area features numerous artisanal mining activities. Several artisanal pits/shafts clusters have been observed and mapped.
  • In this reconnaissance field trip, only a small area was able to be visited. The artisanal workings identified on this visit are in the NE of the permit.
  • The area has a very thick laterite cover overlaying saprolitic material. Several quartz veins have been observed. The artisans are extracting gold from lateritic cover, saprolites and quartz veins.

Next Steps

Kouroussa Permit. Sahara and Volt teams will continue collecting grab samples in the artisanal workings area known as the “World Bank”. Following sampling and assay, an auger drilling geochemical sampling
program will be undertaken in the area highlighted in Figure 3.

Kouroussa West Permit. The teams will execute a systematic soil sampling program to generate initial targets. The soil sampling program will be followed by a shallow auger drilling geochemical sampling program.

Fadougou Permit. Volt’s team will continue collecting grab samples in the area identified to have artisanal workings. The sampling step will be followed by an auger geochemical sampling in the area that has active
and old workings. For the areas that are not disturbed by human activities, the team will conduct a systematic soil sampling program.

Mandiana Project

The Mandiana Project is constituted by the Nzima and Monebo permits. The Nzima permit area surrounds the Nzima gold deposit which is operated by small scale miners.

Desktop Studies
The team has finished the desktop studies for the Mandiana Project. The desktop work included gathering of previous information, geo-referencing, digitization and conducting interpretation of the data to generate initial exploration targets. Further information obtained from this work and next steps will be advised in the near future.

Konsolon Project

The Project is located in a highly prospective gold region with several gold occurrences and artisanal mining activities along with the Nordgold Lefa (Lero) operating gold mine 20km East. Sampling conducted by previous explorers identified a NW-SE trending gold in soil geochemical anomaly within the permit area.

The received data is still under review and further information will be reported in the near future. The geology of the area includes meta-sedimentary rocks of the Lower Proterozoic Birimian Group.

The area is covered by laterites formed on the metamorphized terrigenous and volcanogenic rocks of the Birimian Group. The geology is very analogous with the Lero Gold Mine.

Soil and shafts sampling campaign

The team has developed a soil sampling program in an area that was identified as a NW-SE trending geochemical anomaly by previous explorers. The soilsamples have been planned at a grid of 100m by 500m to cover all the anomalous area with a buffer of 300m – 400m. The program will comprise of 1,800 soil samples and additional samples from sampling of artisanal mining shafts.
